ELECTRODE-PLATE FOR ELECTRIC ACCUIVIULTORS.

S1 ECIFICATION forming part 0f Letters Patent No. 669,240, dated March 5, 1901.

Application filed October 20, 1900. Serial NO. 33,706. (No model.)

To al?, whom, it may concern.:

Be it known that I, HEINRICH FRANZ HOBEL, asubjectof the Emperor of Austria-Hungary, resid ing at the city of Berlin, in the Kingdom 5 of Prussia, German Empire, have made a new and useful Invention in Electrode-Plates for Electric Accumulators, of which the following is a specification.

The invention relates to electrode-plates for 1o electric accumulators of such kind as have been described in my former patent specification, No. 629,363, dated July 23, 1899.

The plate comprises a frame comprising a series of bars from which two series of leaves I5 project, one series extending from the central portions of said bars to the front and the other series to the rear. In the present invention the two series of leaves are not only arranged in staggered relation or alternately in relazo tion to each other, but each series are in staggered relation to the leaves carried by the adjacent bars.

The new electrode-plate is shown in the accompanying drawings.

Figure 1 is an elevation of the improved grid or latticed plate; Fig. 2, a section on the line 2 2 of Fig. l; Fig. 3, a section on the line 3 3 of Fig. l; Fig. 4C, a section on the line 4 4 of Fig. l; Fig. 5, a section on the line 5 5 of 3o Fig. l; Fig. 6, a perspective view of a part broken from the new plate.

The plate comprises a frame consisting of sides l, end cross-bars l, intermediate crossbars 2, and strengthening-ribs 3, extending between bars l and intersecting with bars 2. The inner faces of bar's l and both sides of bars 2 are beveled from their central portions toward their edges, and from these faces leaves 4f project. These leaves, -as clearly shown in Fig. 6, widen toward their outer 4o edges.. Eachbar la and 2 carries two series ot leaves, one series extending from the beveled faces on one side of the central point of the bars and the other series from the other beveled faces. The two series carried by each barare arranged in staggered relation to each other and also in staggered relation with the leaves projecting from the corresponding side of the centers of the adjacent bars.

The new plate may be cast.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isl An electrode-plate comprising a plurality of bars each of said bars having two series of 55 leaves projecting from the same, the leaves of one set of each bar being arranged in staggered relation with the opposite set and the leaves carried by each bar being arranged in staggered relation with the leaves of the bar 6o adjacent thereto.

In witness whereof I have hereunto set my hand in presence of two witnesses.

HEINRICH FRANZ HOBEL.
